BUTTON.

SPECIFICATION forming part of Letters Patent No. 290,321, dated December 18, 1883.

Application filed April 18, 1883. (No model.)

To all whom. it may concern:

Be it known that I, J GEN COsTELLO, of Attleborough, in the county of Bristol and State of Massachusetts, have invented a new and useful Improvement in Buttons; and I do hereby declare the following specification, taken in connection with the accompanying drawings, forming a part of the same, to be a description thereof.

This invention relates to that class of detachable buttons and studs in which the shoe is pivoted or hinged to the post, so that said shoe can be turned or tilted into a position substantially parallel with the post, in order that the button may be conveniently applied and removed, and can be placed parallelwith the button-head to retain the button in position. I

The improvement relates to the means employed for pivoting the shoe to the post; and it consists in countersinking the surface of the upper side of the pivotal plate of the shoe, so as to produce a cavity to receive and form a bearing for the post end, and in securing a spring to the shoe between the post end and the button-head, so as to bear upon the post and hold the same in combination with the shoe, as will hereinafter appear.

The objects of the improvement are to simplify the construction of the pivotal parts of the button and enable them to be more readily combined, and, by sinking the cavity in the pivotal plate, to reduce the distance between the shoe and the button-head when the former is placed parallel with the latter, so that the button shall confine more closely the ends of the cuff, collar, or other article to which it is applied.

Referring to the drawings, Figure l represents a button embodying the improvement, with the shoe turned parallel with the postbody. Fig. 2 shows the same in partial section. Fig. 3 represents in perspective a slotted or bifurcated post having its pivotal end bent at right angles to its body portion. Fig. 4 shows in perspective a pivotal plate adapted to combine with said post. Fig. 5 represents in plan the post placed in said plate. Fig. 6 shows the relative positions of said plate and post when the former is turned parallel with the body of the latter.

A is the button-head, of any preferred construction, to which the post B is secured. O is the shoe, composed of the pivotal plate D and a shell, 0, the edge of which is turned over upon said plate'in a well-known manner. E

.is the spring which engages the angular pivotal bar I) on the end of the post, so as to lock the shoe in its different positions, and so as to hold the post and shoe in connection, said spring being arranged between said bar and the button-head. The post shown in the drawings is slotted or bifurcated, so as to produce the pivotal bar 22 on its end, which end is bent at right angles to the post-body, so that the post may be hinged to the shoe on one side of the center of the latter, whereby the distance between the edge of the shoe and button-head, when the shoe is turned parallel with the postbody, will be greater than it would be were the post hinged to the center of the shoe, thereby allowing a short post to be employed. Preferably the post is also hinged to the shoe, so that the latter will be centrally located on the post-body, when turned parallel with the button-head, as shown by dotted lines in Fig. 2.

As shown in Fig. 4, the pivotal portion of the plate D consists of a cavity, 01, countersunk in the upper face of said plate, the shape of said cavity being such as to receive the post end, and its walls form a bearing therefor. As shown in Figs. 3 and 5, the pivotal end of the post is recessed at b, and, as shown at Figs. 5 and 6, a portion, (2, of the plate D projects into or enters the recess 1), when the parts are in the position shown at Fig. 5, and forms a bearing for the central portion of the bar b.

As shown in Fig. 1, the spring E forms one member of the pivot or hinge, and passes between the arms of the post-body, so as to bear upon the angular bar 6, and the spring is held in the shoe by having its ends extend under the turned edge of the shell 0. In order to give greater force to the spring, and in order that the edge of the shell 0 may be evenly bent over, the plate D is provided with depressions 01 which allow the ends of the spring to be bent below the upper surface of the plate D, or even therewith, thereby straining the spring. The parts are combined by placing the plate D in the shell 0, inserting the pivotal end of the post into the cavity d, placing the spring E over the bar I), and then swaging or bending the edge of said shell over upon the plate and spring. The post is then secured to the button-head. The parts are simple in construction, are readily combined, and are strong and durable. No solder is employed about the pivotal portions, and the pivotal plate D is not slotted in order that the post may be inserted into said plate, as is the case in many buttons, thereby weakening said plate.

By reference to Fig. 2 it will be seen that the bottom of the cavity (1 is in as close proximity to the shell 0 of the shoe as is possible, thereby reducing the distance between the shoe and the button-head, when both are parallel to each other, which is a very desirable feature in buttons of this class.

XVhat I claim, and desire to secure by Letters Patent, is-

1. A button or stud having a post with a pivotal end, a shoe composed of a shell, 0,

and a plate, D, secured thereto, and having a countersunk cavity, (1, adapted to receive and to form a bearing for the post end, and a spring secured to the shoe between said plate and the button-head, bearing upon the post and holding the same in pivotal connection with the shoe, substantially as set forth.

2. A button or stud having a post with a pivotal end, a shoe composed of a shell, 0, and a plate, D, secured thereto, and having a countersunk cavity, (1, adapted to receive and to form a bearing for the post end, and arranged with relation to the shell as described, and a spring secured to theshoe between said plate and the button-head, bearing upon the post and holding the same in pivotal connection with the shoe, substantially as set forth.
